The DePuy Orthopaedics unit of Johnson & Johnson has announced a recall of the ASR™ Hip Implant System used as an implant in hip replacement surgeries. The company recommends that patients with an ASR device contact their surgeon for evaluation of their implant performance.
According to the information available on DePuy.com, data shows that approximately 12% of patients (1 in 8 ) who had received the ASR resurfacing device needed to have revisionary surgery five years after their surgery. Revisionary surgery was also required for 13% of patients that received the ASR total hip replacement.
The DePuy ASR™ Hip Implant System is a metal-on-metal design, which by today’s standard is viewed as less than optimal. After time, these metal parts can wear, causing small particles of metal to shed into the body. Doctors have been treating more and more of these cases in recent years, as is mentioned in this story by the NY Times.
Symptoms include pain, swelling, and problems walking. These symptoms are normal after hip replacement. However, if these symptoms persist or come back after subsiding, it is a sign that there may be a problem such as:
DePuy has stated that it intends to “cover reasonable and customary costs of testing and treatment if you need services, including revision surgery, associated with the recall of ASR” but product liability lawyers recommend that patients contact an attorney prior to accepting any compensation. An experienced product liability attorney at the Stampfle Law Firm can make sure that your rights are protected and that you get the compensation you deserve.
One interesting note is that DePuy decided to discontinue the ASR system in 2009 due to it’s declining demand. An obvious need to focus their efforts on more modern resurfacing techniques.
The ASR device is part of a class of large diameter, monoblock hip resurfacing and replacement devices preferred by surgeons for young patients who may benefit from the stability of the device, thus limiting the chance of repeated dislocation. The DePuy ASR™ Hip Resurfacing System was introduced in 2003 and is only approved for use outside the U.S. The ASR™ XL Acetabular System was first launched in 2004 and has been available worldwide. The risk for revision was highest with women utilizing ASR head sizes below 50 mm in diameter.

Contact your orthopaedic surgeon. If you don’t know who performed your hip replacement surgery, ask your primary care physician or the hospital where you had your surgery. If you are unable to determine the type of implant you received, you can fill out a release form and mail it to the address on the form. This will allow DePuy to contact your surgeon on your behalf.
